Baseus Adaman 140W Test: this external battery has a capacity of 24,000 mAh

It is rare that I do not have a power bank (autonomous large capacity battery) at hand. I use it to charge my devices when I’m on the go, and it’s also a great way to charge several devices at the same time at the hotel.

But with the batteries of laptops and smartphones becoming more and more voluminous, it is essential to have large-capacity autonomous batteries capable of carrying enough energy and delivering it quickly to devices.

Who says greater capacity means greater weight? Well, not necessarily!

But who says greater capacity means greater weight, right? Well, not necessarily! The Baseus Adaman 140W 24000mAh external battery breaks this rule!

Instead of a traditional lithium battery, it uses a high-density carbon-silicon battery that has an energy density 12.8% higher than that of lithium batteries, which means that it can be smaller and lighter.

And that’s not all!

These batteries have a life cycle of more than 1,000 recharges

These batteries have a life cycle of more than 1,000 recharges, which is much more than the approximately 500 recharges that can be expected from a lithium battery. So you save money and you preserve the planet!

A little big, but not huge! Adrian Kingsley-Hughes/ZDNET

I have been using this power bank for a few weeks now and it has impressed me. It has three outputs, one of which has a maximum power of 140 W. It recharges at an incredible speed of 100 W, so quickly that you see the digital display of the capacity increase by a percentage point every 10 seconds!

I have tested all the technical claims of the manufacturer, and you get exactly what it promises!
